Unless you have a sport, health condition or otherwise for which you need to maintain a certain weight, having a “goal weight” is a recipe for disaster.
First, what is “weight” as it pertains to your body? In the most simplistic of definitions, it is the sum of your mass. So, when you add up the amount of water, fat, muscles, poop etc., you get your weight. This number fluctuates minute to minute, day to day based on so many factors not within our control. Did you sleep enough, did you poop, are you on your period, are you stressed, do you have hormonal issues? These are just a few things that impact how much you weigh.
